If a Lasting Power of Attorney (LPA) is in place, it creates clear legal rights and responsibilities for the people involved but only within the limits of the document and the law. The donor (the person who made the LPA) keeps control while they have mental capacity and attorneys can only step in when the LPA is registered and the conditions for using it are met. For Health and Welfare, that trigger is loss of mental capacity. For Property and Financial Affairs, attorneys may be able to act as soon as it is registered but only if the donor allows it and/or if the donor can no longer manage decisions.

This guide from Soteria Estate Planning explains:

· the rights of the donor, attorneys and family members

· the role of each person involved (including certificate providers and the Office of the Public Guardian)

· the real-world triggers for when attorneys step in

· how this plays out across different family types (couples, divorced, blended families, adult children supporting parents)

First: the key people in an LPA (and what they’re there to do)

1) The donor

The donor is the person making the LPA the one whose decisions and wellbeing are being protected.

The donor’s core rights

· To choose who their attorneys are (and whether they must act together or separately). (GOV.UK)

· To set instructions (must-do rules) and preferences (guidance).

· To keep making their own decisions for as long as they have capacity.

· To decide when a Property & Financial Affairs LPA can be used (as soon as registered with their permission vs only after capacity is lost).

· To revoke/cancel the LPA while they have capacity (practically important, especially if family circumstances change). (Legislation.gov.uk)

2) The attorney (the person appointed to act)

An attorney is the person (or people) the donor chooses to make decisions on their behalf under the LPA.

An attorney’s “rights” are really legal powers and they are always limited by:

· the type of LPA (financial vs health)

· the wording in the LPA (instructions/preferences)

· the donor’s capacity and consent rules

· the attorney’s legal duties (best interests, etc.)

Attorney duties (the rule that sits above everything)

Attorneys must act in the donor’s best interests and within the legal framework of the Mental Capacity Act. (Legislation.gov.uk)

What attorneys can do (examples)

· Health & Welfare attorneys can make or help make decisions about daily routine, medical care, and where the donor lives but only once the donor lacks capacity. (GOV.UK)

· Property & Financial Affairs attorneys can manage money and property, pay bills, and make decisions to look after the donor’s home and day-to-day needs. (GOV.UK)

What attorneys cannot do

· They can’t act outside the scope of the LPA. (GOV.UK)

· They can’t use the donor’s money as if it is their own.

· They can’t make large gifts or transfer assets freely as gifting is restricted and closely governed. (GOV.UK)

3) Replacement attorneys

A replacement attorney steps in only if the original attorney cannot act (death, incapacity, unwillingness, etc.).

Why they matter:
If you appoint only one attorney and they can’t act, your LPA can become unusable at exactly the wrong time.

4) The certificate provider

The certificate provider is a built-in safeguard. They confirm the donor:

· understands the LPA, and

· is not under pressure to make it. (GOV.UK)

This becomes especially important in:

· divorced families

· blended families

· situations where one family member is “driving” the process

5) Witnesses

Witnesses confirm the signatures are genuine and properly executed. Witnessing rules matter because many LPA delays come from signing errors.

6) The Office of the Public Guardian (OPG)

OPG is the body that registers LPAs and provides guidance for attorneys.

What OPG effectively does (in plain English):

· registers the LPA (without registration, it cannot be used) (GOV.UK)

· sets practical rules and guidance for attorneys (including around gifting) (GOV.UK)

7) Professionals and organisations (banks, care homes, NHS, councils)

When an LPA is active, these organisations have processes for recognising the attorney’s authority.

For health-related information sharing, there is specific NHS-facing guidance on disclosure to attorneys and deputies. (GOV.UK)

The two LPAs and their triggers: when attorneys can step in

This is the piece most families want spelled out clearly.

Health and Welfare LPA: attorneys’ step in only when capacity is lost

Trigger: the donor does not have mental capacity to make the relevant decision. (GOV.UK)

That means:

· If the donor still has capacity, doctors and care professionals should involve the donor.

· The attorney steps in only when the donor can’t decide for themselves.

Additional practical trigger: the attorney should inform people involved in the donor’s care when they start making decisions. (GOV.UK)

Family example (adult child supporting parent):
Mum has early dementia. Some days she can decide clearly; other days she can’t. A Health & Welfare attorney doesn’t “take over permanently”. Instead they step in decision-by-decision, when Mum cannot decide. (GOV.UK)

Property and Financial Affairs LPA: attorneys may act earlier, but rules still apply

Trigger: the LPA must be registered. (GOV.UK)
After that:

· Attorneys can often act as soon as it is registered, if the donor allows and consents. (GOV.UK)

· Or it may be used only when the donor lacks capacity depending on how it is set up.

Family example (working couple):
A husband finds it hard to use online banking after surgery but still has capacity. A Property & Financial Affairs LPA can allow his wife to handle payments and admin with his permission while he recovers. (GOV.UK)

How “rights” work in practice for each person involved

The donor’s rights in day-to-day reality

Even when the LPA exists and is registered, donors retain important rights:

· Right to autonomy: while they have capacity, their choices come first. (GOV.UK)

· Right to limits: donors can restrict what attorneys can do through instructions. (GOV.UK)

· Right to privacy with protection: donors can choose who will have access to financial decisions and health decisions (they can be different people). (GOV.UK)

Attorneys’ rights and powers

Attorneys have the power to make decisions only as the LPA and law allow.

Property & financial examples of attorney powers

· manage bills and accounts

· pay for care and day-to-day needs

· manage or sell property if necessary (often the most sensitive one) (GOV.UK)

Health & welfare examples of attorney powers

· decide care arrangements and living situation

· make decisions about medical treatment if the donor lacks capacity (GOV.UK)

Family members who are not attorneys: what “rights” do they have?

This is where expectations can clash with reality.

If someone is not appointed as an attorney:

· they do not have automatic legal authority to make decisions

· they may still be consulted, involved, and listened to but they don’t have the decision-making power the attorney has

That is why choosing attorneys can feel emotionally loaded but it is better to choose intentionally than to leave it to crisis.

The “how” attorneys make decisions: jointly vs jointly and severally

If you appoint more than one attorney, the LPA must say whether they act:

· jointly and severally (separately or together): any attorney can act alone or with the others (GOV.UK)

· jointly: all attorneys must agree on every decision (GOV.UK)

· or a mix: some decisions jointly, others jointly and severally (GOV.UK)

Why this matters for families

· Jointly can protect against unilateral action (useful in tense families) but it can also cause delays if one attorney is slow or unavailable.

· Jointly and severally is flexible and practical (often better for day-to-day finances), but it requires trust.

Blended family example:
Dad appoints his new spouse and his adult daughter as joint attorneys. If they must act jointly on everything, even paying care fees can become difficult if they don’t communicate well. Many blended families choose a mixed model: day-to-day actions can be done separately, major decisions jointly. (GOV.UK)

Safeguards and limits: what attorneys must not do

Gifts and transfers: a major misunderstanding

Attorneys have restricted authority around gifting. OPG guidance explains the framework and what happens when attorneys go beyond their authority. (GOV.UK)

Plain English takeaway:
Attorneys can generally pay for the donor’s needs but cannot treat the donor’s assets as a pool to redistribute, reduce inheritance tax, or “help themselves” unless the law and the circumstances clearly allow it.

Record-keeping and accountability

OPG guidance expects attorneys to act properly, and complaints/concerns can be investigated. (GOV.UK)

What happens if the donor disagrees with the attorney?

A properly set-up LPA should reduce conflict but disagreements can still happen.

Key principle: if the donor has capacity, the donor decides.
Attorneys step in only where the donor can’t make the decision (health & welfare) or where the donor has allowed assistance (financial). (GOV.UK)

If the donor still has capacity and feels an attorney is acting wrongly, the donor can revoke the LPA (capacity required) and seek support.

What if there is no LPA who has rights then?

This is often why families seek advice in the first place.

Without an LPA:

· loved ones may have no legal authority to manage finances or make decisions

· families may need to go through the Court of Protection route (deputyship), which is slower and more admin-heavy than having an LPA already in place (and it happens when emotions are already high)

How this works across different family types

Married couples

Common assumption: “My spouse can just take over.”
In reality, an LPA is what makes authority clear and usable especially with banks and care decisions. (GOV.UK)

Good practice: appoint each other, plus a replacement attorney.

Divorced families

Risk: the wrong person ends up as the default decision-maker in practice (or family conflict blocks progress).

Good practice: appoint attorneys aligned with your life now, not your history and be careful about joint vs jointly and severally settings. (GOV.UK)

Blended families

Risk: disputes about care, money and property decisions.

Good practice: clear attorney structure, clear decision-making model, and strong safeguards - the certificate provider step is particularly valuable here. (GOV.UK)

Adult children caring for parents

Risk: urgency and blocked access (banking, care fees, provider conversations).

Good practice: register LPAs early (processing takes time), keep documents accessible and ensure attorneys know what to do when capacity fluctuates. (GOV.UK)

Why Soteria Estate Planning helps here

Most problems with LPAs don’t come from the concept they come from:

· choosing the wrong attorneys

· joint decision models that don’t fit family dynamics

· signing mistakes that delay registration

· not understanding when attorneys can actually step in

Soteria Estate Planning’s role is to translate the rules into a practical plan that works for your family so if and when the time comes, there is no chaos, no guesswork and no avoidable delays.

Strong call to action

If you are thinking “we should get LPAs sorted” – that is usually your cue not to wait. The best time to put an LPA in place is before there is a crisis, while choices are calm and capacity is clear.
